Swiatek and Pegula crash out at Wimbledon

Even the world's best players are not immune to crippling nerves as Iga Swiatek discovered when her Wimbledon dreams were turned to dust in a 7-5 6-7(5) 6-2 quarter-final defeat by Ukrainian wildcard Elina Svitolina.

Svitolina, who returned to the tour in April after giving birth to her daughter last October, was 4-2 down in the opening set and struggled to get her serve going in blustery conditions on Centre Court as Swiatek moved into a 5-3 lead.

But the momentum suddenly swung Svitolina's way as from 0-30 down on her serve in the ninth game she went on to win 16 of the next 18 points to bag the first set and leave stunned Swiatek wondering what had gone wrong.

That sequence included breaking Swiatek's serve twice in succession, with the Polish top seed surrendering the first of those to love with a double fault.

After Swiatek guided a backhand volley into the tramlines to hand Svitolina the set, the players had to endure a 20-minute break as the roof was closed to shut out the dark clouds hovering over Centre Court.

That interlude gave Swiatek a chance to re-evaluate her tactics and she came back to break Svitolina for a 2-1 lead in the second set.

The top seed's 28-year-old rival, however, kept breathing down her neck and made it all square at 3-3 by pounding some ferocious groundstrokes from the baseline.

Swiatek earned two more break points in the ninth game but once those went begging neither player could break the deadlock and they headed into the tiebreak.

Svitolina made a fast and furious start to jump into a 4-2 lead but Swiatek, who saved two match points to beat Belinda Bencic in the previous round, refused to panic and kept faith with her fearsome forehand to rattle her rival.

A backhand error handed Swiatek the set
